Touchscreen has English option, just select the destination and departure time, then continue past the Keikyu Line entrance and take the elevator or escalator down to the bus level and find your departure stop.
look for the widest LCD screens around the arrival hall. it's opposite to the keikyu ticket office and next to monorails. its rather hard to miss that.
or in other words its straight ahead from where you come out airside, before u reach the train stations.
